I think this line from Ben Brooks is a very apt description of the iOS 6 update:

I don’t think this is an update that makes me say “wow” as much as it makes me say “nice”.

For folks who never have their iPhone more than an arm’s reach away, these types of refining software updates are most welcomed. They may not seem like the most amazing thing in the world when you’re only reading about the features, but once you’ve used them there’s no going back. I liken it to the removing of a pea from underneath the mattress.
